Flash data register 0 low (FDR0L)
During program operations, the Flash Address Registers (FARH/L) are used to store the
Flash address in which to program and the Flash Data Registers (FDR1H/L-FDR0H/L) are
used to store the Flash data to program.

This is a replication of B0S bit.
In order to maintain compatibility with the ST10F273E where operations on
the last 2 sectors were flagged in this position.
During any erase operation, this bit is automatically modified and gives the
status of the Bank 0. The meaning of B0S bit is given in the next
Bank (BxS) and sectors (BxFy) status bits
reset at the end of a erase operation if no errors are detected.
These bits must be set during a Sector Erase operation to select the last 2
sectors of Bank0. Besides, during any erase operation, these bits are
automatically set and give the status of the last two sectors of Bank0
(B0F11-B0F10). The meaning of B0Fy bit for Sector y of Bank 0 is given by
the next
These bits are automatically reset at the end of a Write operation if no errors
are detected.
Note: These bits can also be seen as selecting the two sectors of Bank1 for
compatibility with the ST10F273E.
